Wild plants can contain bioactive compounds with potential activity against disease-causing microorganisms. In the Kingdom of Saudi Arabia, there are many plant species that may have antibacterial, antifungal, or antiviral activities, among other properties. We extracted methanol as well water from leaves Breonadia salicina, which is an endangered found in wild Arabia. These extracts were tested bacteria Bacillus subtilis, Pseudomonas aeruginosa, Shigella sonnei, Escherichia coli, and Staphylococcus aureus. Both showed antibacterial all microorganisms, thus, B. salicina leaf extract has antimicrobial agent for preservation foods, instead synthetic chemical compounds. methanolic was more effective than aqueous crude P.
